Erratum: In the feature This Week in the Journal for the October 4, 2006 issue, there was a typo in the last sentence of the Cellular/Molecular summary, titled “PSD-95 and Dendritic Branching In Vitro.” The last sentence should have read as follows: “Thus, it appears that PSD-95 can act as a stop signal for dendrite outgrowth and branching by a process that is activity independent.”
